Are you talking about the Pass-Key system? because the only real way to bypass it is to put in a new ignition.
jegs or summit sell a V.A.T.S bypass module with harness get rid of that crap security. count the hours of your life you wasted waiting for your car to start
It's called VATS bypass and you can get them on eBay cheap.
Pass lock security was not installed on 1991 GM cars. I believe it was 1997/98 it was first installed
Not that I am aware of. Are you sure the body control module is the problem and not the power or grounds. You may even have a bad fan switch.
No you cannot remove the system how ever there are ways to bypass it. You can by pass it at the ignition or you can by pass it at the module.
A route for a diversion is a bypass.

bypass?
I know that in the 1991 Chevy Camaro Z28 the Pass-Key Decoder Module is located right behind the dash on the right hand side. (Passenger side) If you remove the top dash piece. You will see the speaker. just to the left of the speaker you will see/should see a metal bracket. The module is attach it. Just remove the 7mm screw and carefully pull the module up. BE CAUTION NOT TO HIT THE WINDOW. Note: You will find that the module will be hitting a small plastic piece. You can fight with the module or you can just cut out the small plastic. It's up to you. It does not serve any real purpose. Good luck!
there is a guy on line who has all the information you need to build a by pass, find the tdm, buy a bypass from him and follow his installation instructions they quit selling them in 2009 so you have to make a bypass or scrap out the car. they stop working after 10 years. no gm did not have to tell you.
